6 Best Database Courses for Advanced Learners
Choosing a database course at an advanced level means finding material that deepens your existing knowledge while offering practical exercises you can apply at work. On this page you will find six options from Coursera and Udemy, covering topics from advanced Java testing to Oracle PL/SQL certification preparation, each with a listed price ranging from $19.99 to $199.99. The courses are ordered according to our internal ranking, not an external rating, and reflect a mix of programming languages, database platforms and exam‑focused training.
If you already have a solid grounding in SQL or a related language, you may prefer courses that focus on complex query optimisation, PL/SQL development or certification prep. Learners new to a particular technology, such as Perl or IoT‑related data handling, might find the lower‑priced introductions useful before moving on to the more specialised Oracle tracks. Consider the provider, price and the specific skill set each course promises when deciding which one aligns with your goals.

How these 6 courses were chosen
Every course below is a real, currently listed course from Coursera, Udemy, matched to "database" by our catalog and ordered by our CourseAsk score. Courses whose own title names the topic rank above those only tagged with it.
The grade on each entry scores how much the provider publishes about the course before you pay — the length and detail of the description, whether it lists learning outcomes and objectives — and whether a named university or institution stands behind it. A is fully documented and institution-backed; E is little more than a title and a price. Courses with almost nothing published are left ungraded rather than marked down, because an unknown course and a poor one are not the same thing.
There are no star ratings on this page — the course feeds we license do not include them, and we would rather leave a column out than fill it with a number we cannot stand behind. What we do have is price: these range from $19.99 to $199.99, as listed by the provider when we last updated the page.

What the prices here tell you
The 6 priced courses on this page run from $19.99 to $199.99, with the middle of the range around $169.99 — a spread of $180.00. That is a wide gap for one subject. A higher price on this page usually reflects who is behind the course rather than how much material it contains, so it is worth opening two or three at different price points and comparing their syllabus before deciding.
Who is behind these courses
These courses come from Coursera and Udemy. The platforms differ in how they sell: some charge once per course, others expect a subscription, and the listed price is not always what you pay at checkout after a promotion.
Courses versus exam preparation
1 of the entries here are built around a certification exam rather than teaching Database from scratch. They are the right choice only if you already know the material and want to pass a specific exam; if you are starting out, pick one of the taught courses first and come back to exam preparation afterwards.
Before you enrol
Open the provider’s own page and check three things this comparison cannot tell you: when the course was last updated, what the syllabus actually covers in its later sections, and what recent learners say. Prices shown here are the provider’s listed price when we last rebuilt this page on 18 September 2026 — they change often, and a promotion can move them substantially. We earn a commission if you enrol through our links, which costs you nothing and never affects the order courses appear in.
